Four AR surges through 1/13

Tomer’s Take: I’m forecasting four moderate atmospheric river surges through 1/13. Primary beneficiaries are CA, OR, WA, BC. Snow is also likely through the interior Rockies. My forecast video 1/4: Current Setup Visible satellite shows a monster area of low pressure hitting the West Coast with a firehose of moisture. Notice how well-defined the area […]

Three more AR surges through 1/12

Tomer’s Take: I’m tracking three moderate intensity atmospheric river (AR) surges through 1/12. Biggest totals occur in CA, WA, OR, BC. Current Setup Infrared satellite shows the Pineapple Express and low pressure systems lined-up. Forecast Pattern Forecast jet stream valid 1/12 shows a choppy jet stream with well-defined dips and ridges. This pattern favors the […]

Snow forecast through 1/11

Tomer’s Take: The atmospheric river (AR) continues through 1/11 with the biggest impacts in CA, WA, OR. A moderate intensity AR surge occurs in CA 1/4-1/5. This storm impacts UT, WY, ID, CO on 1/5-1/6. There appears to be another moderate intensity AR surge for CA/West Coast on/around 1/10. 7-Day Totals: Brighton, UT is reporting […]

What does 2023 hold?

Tomer’s Take: 2023 features a continuation of the atmospheric river through 1/9. A moderate level intensity moisture surge occurs on 1/4-1/5 in CA, OR, WA. The jet becomes choppy through UT, WY, and CO on/after 1/4 with some ridge stress cutting down on snow totals. My forecast video 1/1: Current Setup Infrared satellite shows the […]

New Year’s Atmospheric River through 1/9 with a twist

Tomer’s Take: The atmospheric river (AR) continues through 1/9, but the storm systems weaken 1/3-1/9 once they move into UT, CO, NM. Snow levels remain elevated in the Sierra because of this warm, moist AR. They’re also elevated on 12/31 in the Wasatch with rain reported at the base of Park City. Snow levels should […]

Snow forecast through 1/8

Tomer’s Take: The atmospheric river now looks to continue through 1/8. Feet of additional snow accumulation likely in CA, UT, WY, CO. But, the 2nd period appears to generate less snow for UT than previous updates. My forecast video 12/30: Current Setup Infrared satellite shows the Pineapple Express and parade of low pressure systems lined-up […]

Atmospheric River through 1/7

Tomer’s Take: The atmospheric river continues through 1/7. The next surge 12/30-1/1 is ‘moderate to strong’ intensity. Feet of grand total snow. My forecast video 12/29: Current Setup Infrared satellite shows the Pineapple Express and parade of storm systems lined-up through 1/7. Forecast Pattern Forecast jet stream valid 1/6 shows the west to east jet […]

Atmospheric River through 1/6

Tomer’s Take: It now looks like the atmospheric river (AR) continues through 1/6 generating feet of grand total snow across the West. Awesome sunrise view at Palisades Tahoe this morning in-between storm systems. The first storm system delivered 13-22 inches of snow at higher elevations with a rain/snow problem lower. My forecast video 12/28: Current […]

Feet of accumulation through January 4

Tomer’s Take: A powerful atmospheric river remains on track for the West through 1/4. Grand totals of 1-5 feet (or more) for PNW, BC, CA, UT, WY, and CO. -> See below for my forecast grand totals and snow timeline for the Wasatch. My forecast video 12/27: Current Setup Infrared satellite shows the storm track […]

Big totals with a powerful 9-day Atmospheric River

Tomer’s Take: Data continues to suggest a “strong to extreme” intensity atmospheric river (AR) 12/27-1/4 for most of the West. Grand totals (see below) of 1-5 feet or more. My forecast video 12/26: Current Setup Water vapor satellite shows the organizing atmospheric river reaching all the way into the western Pacific. This is the Pineapple […]
